If you are into norse mythology and vikings - there is a superb comic called "Valhalla" which was released in 12 or 13 volumes. Written in Danish but I read a Swedish version as a kid, if you can find it in Swedish it is a pure joy to read. Not only does it retell many of the norse tales about their Gods the artwork is pretty neat as well!

They made an animated movie out of the first album, which can be viewed at YouTube with English subtitles. 7x10minutes or something like that.

Though it is based on the very first album and does pretty much only feature Thor and Loki and the giants. Each of the other albums usually focuses on one of the gods for the main story but features a core of reoccurring characters like Thor and Loki (Loki who often get himself or the others in trouble).

I really liked because they were quite cleverly written, teaching norse mythology in a fun way, and not only about the gods but about other stuff as well like the Fenris wolf, the giants and the midgard serpent.

It's a damn shame if there aren't any English translation of those comics!
